Here's why:
* Ethos: Establishing credibility and trustworthiness: Paine is positioning himself as a credible source by claiming to rely on facts, logic, and common sense – things that are generally perceived as objective and unbiased. This appeals to the audience's trust in reason and straightforwardness.
* Contrast with opposing arguments: The phrase implies that other arguments, which Paine might consider less persuasive, are relying on something other than facts, logic, and common sense. This sets up a contrast that further strengthens his own position.
* Direct address to the audience: By directly addressing the audience ("I offer nothing more…"), Paine establishes a sense of connection and encourages them to engage with his arguments on a level of shared values.
In summary, by employing ethos, Thomas Paine aims to establish himself as a reliable and trustworthy source for the reader, making his arguments more persuasive.
